How to Plan for a Clean Server Migration?
When transferring data to a more resilient server, virtualization, or cloud hosting, you’ll confront many questions as your company works to make its IT systems more productive on server-migration.
Server migrations have become an essential part of today’s IT environment, as everyone demands quick installations and minimal downtime.
The speed and efficiency with which you can migrate your servers will be crucial in reaching your company’s future development potential. If you’re unsure what a server migration is or what aspects are involved in the process, we’ll walk you through it stepwise.
What is Server Migration?
The process of moving data from one server to another is known as server migration. Security issues, equipment breakdowns, outdated servers, and other factors can lead to server migrations.
Why Should You Consider a Server Migration?
Server migrations are essential for various reasons. Organizations might choose to migrate in order to:
- Leverage new technology or enhanced services to ensure the OS and hardware stay relevant.
- Increase flexibility and scalability by moving to cloud-based solutions.
- Reduce and consolidate hosting costs.
- Replace outdated infrastructure nearing the end of its useful life.
- Minimize load at a single location, ensuring high availability through extended and distributed hosting.
Different Types of Server Migrations
- Mail Server Migration
This involves extracting and moving all emails, contacts, calendars, and other data from one email host to another. - Virtual Server Migration
Virtual server migration refers to transferring the resources of a physical server—like its OS, files, data, and applications—to a new virtual machine on a virtualized platform. - Azure Cloud Migration
With Microsoft Azure as an Infrastructure-as-a-Service (IaaS) platform, large and small enterprises can enjoy the benefits of a public cloud, enhancing efficiency and reducing costs. - Cloud Server Migration
This process transfers all data, applications, and business systems from on-premises servers to a cloud environment.
Steps to Prepare for Server Migration
- Prepare Your New Server
The new server should accommodate all the data for your website and applications. Ensuring the right configuration and installing essential tools will help the new environment support your sites.TIP: Make sure there’s extra storage space during migration to handle incoming data and support growth. - Check Data Integrity
Verifying data accuracy before and after migration is crucial. Even minor data loss can significantly affect site or app performance.TIP: Create a full external backup of your site before migrating to ensure data security. - Data Transfer
Data transfer, often the most time-consuming stage, depends on the bandwidth between your old and new servers. Greater bandwidth enables faster migration.TIP: Inform all site users about the migration schedule and expected downtime. - Quality Assurance (QA) Testing
Conduct extensive testing to ensure full functionality and data accuracy post-migration. It’s time well spent to catch issues early.TIP: Compare your new setup with your previous server to identify any missing elements. Migrations can reveal pre-existing site issues! - DNS Change and Go-Live
Changing DNS is generally straightforward but should occur during low-traffic times, like at night or on weekends.TIP: Notify your DNS provider about the migration schedule and DNS switch plans.
What to Avoid During Server Migration
- Avoid migrating during critical business periods to prevent minor issues from escalating.
- Schedule migrations during off-peak hours to minimize disruptions.
- Complete all necessary assessments before migration. Incomplete assessments often lead to preventable issues.
- Communicate with all relevant staff about migration timelines, adjustments, and roles.
Although server migrations may appear straightforward, executing them successfully requires careful planning. By following each step and engaging experts, you can achieve a smooth, effective migration that minimizes risks and maximizes benefits.
